A relatively new way of analysing fiscal policy by identifying the financial costs and benefits of government policies to people of different ages, now living or yet to be born. Fiscal policy can distribute resources between different generations, sometimes deliberately and often inadvertently. At any moment in time, one generation may be in work and paying taxes that support other generations (those at school or retired) that are not working. Over its lifetime, one generation's mix of taxes paid and benefits received may differ sharply from that of another generation. Politicians are often tempted to ignore the needs of future generations (who, clearly, cannot vote at the time) in order to win the support of current generations, for instance by borrowing heavily to fund current spending. More fundamentally, because it incorporates all the tax and spending, current and future, to which a government is committed, generational accounting is a much better guide to whether fiscal policy is sustainable than measures such as the budget deficit, which looks only at taxes and spending in the current year.
